DC 8205 · 38 CFR 4.124a
Fifth (Trigeminal) Cranial Nerve, Paralysis of C&P Exam Prep
To document the current severity of trigeminal nerve paralysis or dysfunction under 38 CFR 4.124a DC 8205, capturing both sensory and motor manifestations to establish a compensable rating of 10%, 30%, or 50%.
- Format:
- Interview + Physical
- Typical duration:
- 30-45 minutes
- DBQ form:
- Cranial_Nerve_Conditions (Cranial_Nerve_Conditions)
- Examiner:
- Neurologist or Physician
What the examiner evaluates
- Degree of facial sensory loss across all three trigeminal divisions (ophthalmic V1, maxillary V2, mandibular V3)
- Motor function of muscles of mastication (masseter, temporalis, pterygoids) including jaw deviation, atrophy, and bite force
- Presence and character of pain - constant excruciating, intermittent, or dull
- Paresthesias and/or dysesthesias in the face, scalp, teeth, gums, sinuses, or tongue
- Numbness distribution and severity across trigeminal dermatomes
- Difficulty chewing, swallowing, or speaking attributable to trigeminal dysfunction
- Changes in salivation (increased or decreased)
- Corneal reflex integrity (V1 branch function)
- Jaw reflex and deep tendon reflexes of masticatory muscles
- Whether paralysis is complete or incomplete (and if incomplete, whether severe or moderate)
- Laterality - unilateral vs. bilateral involvement
- Functional impact on work, daily activities, and social functioning
- Relevant diagnostic studies such as MRI, nerve conduction studies, or EMG
The examination will include a history interview followed by a structured neurological physical examination. The examiner will test facial sensation with light touch and pinprick across all three divisions, assess jaw motor function, evaluate reflexes, and document any autonomic symptoms. Bring all prior neuroimaging reports, EMG/nerve conduction results, and treatment records to the exam.
Measurements and tests
Facial Sensation Testing - Light Touch and Pinprick
What it measures: Integrity of the sensory fibers of V1 (forehead/eye), V2 (cheek/upper lip/upper teeth), and V3 (lower jaw/lower lip/lower teeth/anterior tongue) distributions
What to expect: The examiner will use a cotton wisp and/or a sharp object to test sensation bilaterally across each division. You will be asked to report whether the sensation feels normal, reduced, absent, or abnormal (burning, pins and needles).
Critical thresholds
- Complete absence of sensation in all three divisions bilaterally with complete motor loss 50% - Complete paralysis
- Marked/severe sensory loss in multiple divisions with significant motor involvement (jaw weakness, deviation, atrophy) 30% - Incomplete, severe paralysis
- Moderate sensory deficits (reduced but not absent) with minimal or no motor involvement 10% - Incomplete, moderate paralysis
Tips
- Report exactly what you feel - do not guess. If sensation feels different (not just absent), say 'it feels abnormal' or 'like a buzzing feeling instead of a normal touch.'
- If sensation varies by time of day or with triggers, tell the examiner before testing begins.
- Do not brace for the touch and deliberately suppress your response - answer honestly and immediately.
Pain considerations: If light touch or pinprick provokes pain or electric-shock sensations (allodynia/hyperalgesia), immediately tell the examiner. This is a critical finding that affects severity rating.
Corneal Reflex Testing
What it measures: Function of the V1 (ophthalmic) branch of the trigeminal nerve; the afferent limb of the corneal blink reflex
What to expect: The examiner may lightly touch the outer edge of your cornea with a wisp of cotton. A normal response is a bilateral blink. Absence or asymmetry of the reflex indicates V1 branch dysfunction.
Critical thresholds
- Absent corneal reflex ipsilateral to affected side Supports incomplete or complete paralysis finding; contributes to severity assessment
Tips
- Do not intentionally blink or resist - allow the natural reflex to occur.
- Tell the examiner if you have worn contact lenses that may have reduced corneal sensitivity over time.
- If your eye feels abnormally dry or you have had corneal complications, mention this as it is a consequence of trigeminal V1 dysfunction.
Pain considerations: If the corneal touch triggers pain rather than just a blink, report this immediately as it may indicate aberrant nerve regeneration or hypersensitivity.
Jaw Motor Function Assessment
What it measures: Motor branch of V3 (mandibular division); function of masseter, temporalis, medial and lateral pterygoid muscles responsible for chewing and jaw movement
What to expect: The examiner will ask you to clench your teeth (testing masseter/temporalis), open your jaw against resistance, and move your jaw side-to-side. They will observe for jaw deviation toward the weakened side, and may palpate for muscle atrophy.
Critical thresholds
- Complete jaw paralysis - unable to close mouth or chew; significant masseter/temporalis atrophy visible Supports 50% complete paralysis rating
- Marked jaw weakness with deviation, difficulty chewing solid foods, palpable atrophy Supports 30% incomplete, severe paralysis
- Mild-to-moderate jaw weakness, no significant atrophy, can chew with difficulty Supports 10% incomplete, moderate paralysis
Tips
- On your worst day, your jaw weakness may be more pronounced - be sure to describe how chewing ability fluctuates, not just how it is at this single moment.
- Mention any diet modifications you have made (e.g., eating only soft foods, cutting food into small pieces, avoiding hard foods) as these are functional indicators of motor severity.
- If your jaw deviates when you open it, point this out to the examiner if they have not already noted it.
Pain considerations: Jaw clenching or chewing may provoke or worsen facial pain. Tell the examiner if the motor testing itself causes pain or if sustained chewing causes pain flares.
Jaw Jerk Reflex
What it measures: Integrity of the trigeminal motor and sensory pathways; the only deep tendon reflex mediated entirely by a cranial nerve
What to expect: The examiner may tap the chin lightly with a reflex hammer while your jaw is slightly open and relaxed. The reflex is normally absent or minimal in adults; an exaggerated jaw jerk suggests upper motor neuron involvement, while an absent reflex in context of other findings supports peripheral nerve damage.
Critical thresholds
- Absent jaw reflex with other trigeminal signs Corroborates peripheral trigeminal nerve damage; supports paralysis classification
Tips
- Relax your jaw completely during this test.
- Report if you have jaw clicking (TMJ) as this may confound the examiner's assessment.
Pain considerations: If the reflex test provokes a pain episode (e.g., triggering tic douloureux-type pain), report this immediately.
Autonomic Symptom Assessment - Salivation and Lacrimation
What it measures: Integrity of autonomic fibers traveling with trigeminal branches; decreased salivation relates to V3 involvement, while lacrimation changes relate to V1/V2 autonomic fibers
What to expect: The examiner will ask about dry mouth, excessive drooling, or dry eyes as part of the history. There may be no formal bedside test, but your reported symptoms are recorded on specific DBQ checkboxes for decreased salivation and gastrointestinal symptoms.
Critical thresholds
- Clinically significant decreased salivation affecting swallowing or oral health Corroborates V3 motor/autonomic involvement; supports higher severity classification
Tips
- Keep a log of how often you experience dry mouth, difficulty swallowing dry foods, or excessive drooling before the exam.
- Mention if you have had dental complications (cavities, gum disease) related to dry mouth, as these are objective consequences of the condition.
- Note whether symptoms are constant or triggered by eating and talking.
Pain considerations: Dry eye from decreased lacrimation can cause corneal pain and photophobia - document these as separate functional consequences of trigeminal nerve damage.
Rating criteria by percentage
50%
Complete paralysis of the fifth cranial nerve. This represents total loss of trigeminal function including complete anesthesia of the face, loss of corneal reflex, complete paralysis of muscles of mastication, and loss of autonomic functions subserved by the nerve. Both sensory and motor functions are entirely absent.
Key symptoms
- Complete absence of facial sensation in all three divisions (V1, V2, V3)
- Complete paralysis of all muscles of mastication - unable to chew
- Absent corneal reflex - risk of corneal ulceration
- Complete jaw drop or inability to close mouth due to pterygoid/masseter paralysis
- Marked masseter and temporalis muscle atrophy
- Absent jaw jerk reflex
- Complete loss of sensation to anterior two-thirds of tongue (lingual nerve branch of V3)
- Significant decreased salivation
- Total inability to eat solid foods
- High risk of corneal injury due to absent protective reflex
From 38 CFR: 38 CFR 4.124a DC 8205: 'Complete - 50.' The rating note specifies this is 'dependent upon relative degree of sensory manifestation or motor loss,' meaning both sensory and motor components are evaluated together to reach the complete paralysis threshold.
30%
Incomplete, severe paralysis of the fifth cranial nerve. Substantially impaired function across sensory and/or motor domains, but not reaching complete loss. This may include marked sensory deficits across multiple divisions combined with significant motor impairment of mastication, or severe sensory dysfunction alone with highly disabling symptoms.
Key symptoms
- Markedly reduced facial sensation across multiple trigeminal divisions
- Severely diminished corneal reflex with corneal vulnerability
- Significant jaw weakness with jaw deviation on opening
- Difficulty chewing most solid foods - significant dietary restriction required
- Palpable masseter or temporalis atrophy
- Severe paresthesias or dysesthesias (burning, electric shocks, crawling sensations) across face
- Frequent or near-constant pain episodes across face
- Decreased salivation significantly affecting swallowing
- Numbness severe enough to cause functional impairment (biting cheek/tongue, dental injury due to lack of protective sensation)
- Severe interference with occupational and daily functioning
From 38 CFR: 38 CFR 4.124a DC 8205: 'Incomplete, severe - 30.' Per M21-1 guidance, 'severe incomplete paralysis' anticipates substantially less impaired function than complete paralysis but with marked objective deficits in both sensory and motor domains, or extreme sensory disability. The rating note emphasizes that the relative degree of sensory manifestation AND motor loss are both considered.
10%
Incomplete, moderate paralysis of the fifth cranial nerve. This is the maximum evaluation reserved for the most significant cases of sensory-only impairment per M21-1 guidance, or moderate combined sensory and motor dysfunction. Symptoms are real and documented but do not rise to the severe threshold.
Key symptoms
- Reduced but not absent facial sensation in one or more divisions
- Mild-to-moderate difficulty chewing hard foods only
- Intermittent facial pain or paresthesias
- Mildly reduced corneal reflex
- Minimal to no jaw muscle atrophy
- Mild jaw weakness without significant deviation
- Intermittent numbness or tingling affecting portions of the face
- Symptoms present but with limited impact on daily function
- Reduced or abnormal sensation affecting a limited distribution area
From 38 CFR: 38 CFR 4.124a DC 8205: 'Incomplete, moderate - 10.' Per M21-1, moderate is the maximum evaluation for purely sensory impairment. If the objective findings show only sensory deficits (no motor atrophy, normal jaw strength, no significant reflex loss), the rating cannot exceed 10% regardless of the examiner's subjective assessment of severity.
Describing your symptoms accurately
Facial Pain
How to describe it: Describe the pain type accurately: constant and excruciating (maps to DBQ field A), intermittent shooting or electric-shock pain (field B), or dull aching pain (field C). Specify which areas of the face are affected using anatomical landmarks - forehead, cheek, upper jaw, lower jaw, teeth, gums, lips, or tongue. State whether triggers exist: chewing, talking, wind, light touch, brushing teeth.
Example: On my worst days, I experience constant burning pain across my entire right cheek and lower jaw that rates 9 out of 10. Even a light breeze on my face triggers an electric-shock sensation that lasts several minutes and forces me to stop whatever I am doing. I cannot eat, speak comfortably, or concentrate when these episodes occur.
Examiner listens for: The examiner is listening for whether the pain is constant vs. intermittent, the severity rating, the distribution (which division of the trigeminal nerve), functional consequences such as inability to eat or speak, and whether the pain is triggerable by light touch (which indicates allodynia and suggests significant nerve pathology).
Avoid: Do not say 'it's just some tingling' when you experience disabling pain episodes. Do not minimize the impact by saying 'I manage it okay' if in reality you have changed your diet, sleep position, or daily routine because of the pain.
Numbness and Sensory Loss
How to describe it: Specify the exact location of numbness using clear landmarks: 'My right cheek from the nose to the ear feels like it has been novocained,' or 'The right side of my lower lip and gum is completely numb.' Distinguish between complete numbness (no sensation at all) and partial numbness (reduced but present sensation). Note whether this causes secondary problems like biting your cheek, burning your mouth with hot food, or dental injuries.
Example: The numbness on my right side is constant. I have bitten the inside of my cheek multiple times because I cannot feel it. I burned my tongue with hot coffee because I could not detect the temperature. My dentist has noted I have developed cavities on the numb side because I cannot feel early dental pain.
Examiner listens for: Distribution across V1, V2, and V3 territories; whether numbness is complete or partial; functional consequences of sensory loss (injury, falls due to not feeling pain warnings, dental complications); whether the pattern is consistent with peripheral nerve damage vs. central pathology.
Avoid: Do not say 'a little numb' when you mean completely anesthetic. Do not omit the functional consequences of numbness - the examiner needs to understand what the numbness prevents you from doing safely.
Difficulty Chewing
How to describe it: Be specific about which foods you cannot chew, how long chewing fatigues your jaw, and whether jaw weakness causes food to fall out of your mouth. Describe diet modifications: 'I can only eat soft foods like mashed potatoes, yogurt, and soup. I cannot eat steak, apples, or any food that requires sustained biting force.' Quantify impact: 'Meals that used to take 15 minutes now take 45 minutes or I skip eating.'
Example: On my worst days, my jaw fatigues after just two or three chews. I have to cut everything into tiny pieces and swallow with minimal chewing. I have lost significant weight because eating is so difficult and painful that I avoid it. I rely almost entirely on liquid nutrition supplements.
Examiner listens for: Specific functional limitations in mastication, diet modification, weight loss, jaw fatigue, deviation of the jaw on opening, and whether weakness is primarily muscular (motor V3) or limited by pain.
Avoid: Do not say 'I have some trouble eating' without specifying what foods you cannot eat, what adaptations you have made, and how this affects your nutrition and weight.
Paresthesias and Dysesthesias
How to describe it: Paresthesias are abnormal sensations (tingling, pins and needles, crawling) while dysesthesias are unpleasant abnormal sensations (burning, electric shocks, painful tingling). Describe which you experience, where, how often, and what triggers or worsens them. Example: 'I constantly feel like ants are crawling across my left cheek. When I touch it, it feels like an electric shock.'
Example: My entire left side of my face feels like it is on fire all day. Brushing my teeth, washing my face, or even the pillow touching my cheek at night causes severe burning sensations that wake me from sleep two to three times per night.
Examiner listens for: Type of abnormal sensation (paresthesia vs. dysesthesia), distribution, constancy vs. intermittency, triggers, and whether the sensations interfere with sleep, hygiene, work, or social interaction.
Avoid: Do not conflate normal trigeminal neuralgia pain with paresthesias - be precise about the sensation type. Do not omit that abnormal sensations occur at night or during hygiene activities.
Functional Impact on Daily Life
How to describe it: Describe how the trigeminal nerve condition limits specific activities: eating, speaking, dental hygiene, facial grooming, wearing glasses, exposure to wind or cold, sleep, work duties, and social interactions. This information directly populates the functional impact field on the DBQ and is critical for the rating.
Example: On my worst days, I cannot eat solid food, I avoid speaking in groups because talking worsens my facial pain, I cannot brush my teeth on the affected side without triggering a pain episode, and the cold air outside causes such severe facial pain that I am essentially homebound in winter. I have missed work four to six days per month because of these episodes.
Examiner listens for: Specific occupational limitations, social restrictions, frequency of lost workdays, impact on self-care, and any secondary complications (weight loss, social isolation, dental disease, corneal injury) that demonstrate the real-world severity of the nerve dysfunction.
Avoid: Do not give a general answer like 'it affects my quality of life.' Provide concrete, specific examples with frequency and duration. The DBQ has a dedicated field for functional impact - the examiner must document this accurately.
Common mistakes to avoid
Only describing symptoms as they are on an average day rather than the full range including worst days
Why: The VA rates based on the severity of the condition, including during flare-ups and worst presentations. Reporting only average-day symptoms may lead to a rating that underrepresents the true disability.
Do this instead: Explicitly tell the examiner: 'My symptoms vary. On my best days I experience [X], but on my worst days I experience [Y]. The worst days occur approximately [frequency].' Per M21-1 guidance, the examiner must capture the full picture including flare-up severity.
Impact: 30% vs 10% or 50% vs 30%
Describing only sensory symptoms and omitting motor symptoms when both are present
Why: Under DC 8205, the rating note explicitly states the evaluation depends on the 'relative degree of sensory manifestation OR motor loss.' Under M21-1, if the examiner assesses only sensory impairment, the maximum rating is 10% (moderate). Motor involvement is required to reach 30% or 50%.
Do this instead: Proactively mention jaw weakness, chewing difficulty, jaw deviation, and muscle atrophy alongside sensory complaints. If you have had diet modifications due to chewing problems, mention these as functional evidence of motor involvement.
Impact: 30% and 50%
Failing to specify which divisions of the trigeminal nerve are affected
Why: The trigeminal nerve has three distinct branches. The DBQ and the rating criteria depend on documentation of which divisions are involved. Vague descriptions like 'my face hurts' do not adequately capture the extent of involvement.
Do this instead: Learn the anatomy before your exam: V1 covers the forehead and eye area, V2 covers the cheek and upper lip, V3 covers the lower jaw and lower lip. Describe symptoms by location using these anatomical regions so the examiner can document each division accurately.
Impact: All levels
Not mentioning secondary complications such as corneal injury, dental disease, weight loss, or nutritional deficits
Why: These complications are objective evidence of the functional severity of trigeminal nerve damage and directly support higher ratings. Corneal injury from absent reflex supports V1 severity; dental disease from numbness supports V3 severity; weight loss supports motor chewing disability.
Do this instead: Bring documentation of corneal complications from your ophthalmologist, dental records noting numbness-related decay, and any records of unintentional weight loss. Mention all secondary health consequences during the interview.
Impact: 30% and 50%
Agreeing with an examiner's minimizing characterization during the exam without correction
Why: Per M21-1, the rating activity - not the examiner - determines the final severity level. However, if the examiner documents mild when the findings are moderate or severe, the veteran must ensure their actual symptoms are accurately recorded in the DBQ.
Do this instead: If the examiner says 'this looks mild,' politely clarify: 'I want to make sure my worst-day symptoms are on record - on bad days I experience [specific severe symptoms].' Do not simply agree with a characterization that does not reflect your full experience.
Impact: All levels
Failing to bring prior imaging and nerve conduction study results
Why: The DBQ includes specific fields for diagnostic study results. Per M21-1, EMG or nerve conduction studies are relevant to peripheral nerve evaluations and are reviewed to corroborate the extent of paralysis. If favorable prior results exist in your records, they must be available for the examiner to review.
Do this instead: Bring copies of all MRI reports, CT scans, EMG results, nerve conduction studies, and neurology consultation notes. The examiner documents these under the diagnostic studies section and they become part of the evidentiary record used in rating.
Impact: All levels
Prep checklist
- critical
Request and review your complete claims file (C-file) and medical records
Obtain copies of all relevant records: neurology notes, MRI/CT of brain and trigeminal pathway, EMG/nerve conduction studies, dental records, ophthalmology notes regarding corneal complications, and any records documenting diet modifications or weight loss. Review these to identify the strongest objective evidence of your current severity.
before exam
- critical
Keep a symptom diary for 2-4 weeks before the exam
Document daily: which areas of your face are numb or painful, severity on a 0-10 scale, duration of pain episodes, what triggers symptoms (chewing, talking, cold, touch), functional limitations (foods avoided, activities curtailed, work missed), and sleep disruption. Bring this diary to the exam as objective evidence of symptom variability and worst-day severity.
before exam
- critical
Identify and document all three trigeminal nerve division symptoms separately
Review the anatomy of V1 (forehead, eye, cornea, scalp), V2 (cheek, upper lip, upper teeth/gums, nasal passages), and V3 (lower jaw, lower lip, lower teeth/gums, anterior tongue, chin, muscles of mastication). Write down specific symptoms in each territory so you can accurately describe each division to the examiner.
before exam
- critical
List all functional limitations caused by the trigeminal nerve condition
Create a written list: foods you cannot eat, activities requiring facial sensation you have modified, dental procedures you have needed due to numbness-related injury, corneal incidents, social and occupational limitations, sleep disruption frequency, and any assistive devices or dietary supplements you use. The functional impact field on the DBQ is critical.
before exam
- recommended
Document all current treatments and their effectiveness
List all medications for trigeminal symptoms (carbamazepine, gabapentin, oxcarbazepine, amitriptyline, topical agents), surgical or interventional procedures (microvascular decompression, rhizotomy, Gamma Knife), and any other treatments. Note whether treatments have reduced symptoms and by how much, or if symptoms persist despite maximum treatment.
before exam
- recommended
Understand the bilateral rating rule
38 CFR 4.124a states that cranial nerve ratings are for unilateral involvement. If you have bilateral trigeminal nerve involvement, the ratings are combined without the bilateral factor. Ensure you can clearly describe which side or sides are affected and whether symptoms differ between sides.
before exam
- optional
Check your state's law on recording C&P examinations
Many states permit veterans to record their C&P examination. Research your state's law and the VA facility's policy. If permitted, prepare a small audio recorder or use your smartphone. Recording creates an accurate record of what you reported and what the examiner documented.
before exam
- critical
Do not take extra pain medication before the exam to artificially suppress symptoms
Take only your normal prescribed medications at your usual times. Taking additional doses to feel better for the exam will result in the examiner documenting you as less impaired than your true baseline. The exam should reflect your actual, typical condition.
day of
- critical
Arrive with your written symptom summary and bring all medical records
Organize your documents: symptom diary, list of functional limitations, medication list, and copies of relevant diagnostic reports. Hand the examiner your written summary at the start of the interview and ask that it be incorporated into the DBQ.
day of
- recommended
Bring evidence of diet modifications and secondary health consequences
If you have lost weight due to difficulty chewing, bring recent weight records or a note from your primary care physician. If you have had dental work related to numbness-induced injury, bring dental records. If you have corneal issues, bring ophthalmology records.
day of
- optional
Eat a meal before your exam if possible to observe chewing difficulty
Attempting to eat a regular meal before your exam may help you accurately describe how chewing difficulty presents. However, if chewing causes a pain flare, the flare may still be active during the exam - which is acceptable as it demonstrates your actual condition.
day of
- critical
Describe your worst-day symptoms, not your best-day symptoms
Proactively tell the examiner: 'I want to make sure my worst-day experience is documented.' Describe the most severe pain episodes, the most extensive numbness, and the most significant functional limitations you have experienced - these reflect the true burden of your condition and are relevant to the rating.
during exam
- critical
Accurately report sensory testing findings - do not suppress or exaggerate responses
When the examiner tests sensation with cotton, pinprick, or temperature, respond immediately and honestly. If a touch feels normal, say normal. If it feels absent, say absent. If it feels abnormal (burning, buzzing, electric), describe it precisely. Accurate responses are critical to documenting the true extent of sensory impairment.
during exam
- critical
Mention all three trigeminal divisions and both motor and sensory symptoms
Do not wait to be asked about each specific symptom. At the beginning of the interview, state: 'I have symptoms in my forehead/eye area, my cheek, and my lower jaw. I have both numbness and pain, and I have difficulty chewing.' This frames the evaluation to capture all relevant domains.
during exam
- critical
Report the functional impact on work and daily activities with specific examples
The DBQ has a dedicated field for functional impact. When asked about impact, give specific examples: 'I have missed X days of work per month,' 'I cannot perform my job duty of [specific task] because [reason],' 'I can no longer [activity] without [consequence].'
during exam
- recommended
Correct any apparent misunderstanding or omission before leaving the exam room
Before the exam ends, ask the examiner: 'Were you able to document all of my symptoms, including [key symptoms]?' If something important was omitted, politely raise it. You cannot easily correct the DBQ after the examiner submits it.
during exam
- critical
Write a detailed summary of the exam immediately afterward
As soon as you leave the exam, write down everything you remember: what you told the examiner, what the examiner observed, what tests were performed and the examiner's apparent reactions, and anything you feel was not adequately captured. This record may be useful if you need to file a supplemental claim or appeal.
after exam
- critical
Request a copy of the completed DBQ
You have the right to request a copy of the completed Disability Benefits Questionnaire. Submit a written request to the VA facility that conducted your exam. Review it carefully to verify that your reported symptoms and the examiner's clinical findings are accurately and completely documented.
after exam
- recommended
File a nexus letter or buddy statements if the DBQ is incomplete or inaccurate
If the DBQ does not accurately reflect your symptoms or the examiner's documented findings are inconsistent with your experience, consider obtaining a private independent medical opinion (IMO) or nexus letter from your treating neurologist. Buddy statements from family members who witness your daily limitations can also supplement the record.
after exam
Your rights during a C&P exam

- You have the right to a higher-level review or Board appeal if you disagree with the rating assigned following your C&P examination.
- If your trigeminal nerve condition is bilateral, you have the right to have each side rated separately and combined without the bilateral factor under 38 CFR 4.124a.
- You have the right to seek assistance from a VA-accredited claims agent, Veterans Service Organization (VSO), or accredited attorney at no cost during the claims and appeals process.
Related conditions
- Fifth (Trigeminal) Cranial Nerve, Neuralgia DC 8405 rates trigeminal neuralgia (including tic douloureux) under 38 CFR 4.124a. Tic douloureux may be rated up to the level of complete paralysis under DC 8405. Veterans with predominantly pain-based trigeminal disorders should ensure the correct DC is applied.
- Seventh (Facial) Cranial Nerve, Paralysis of The facial nerve (CN VII) runs anatomically adjacent to the trigeminal nerve and may be co-affected by the same pathology (e.g., acoustic neuroma, skull base trauma, demyelinating disease). Separate ratings may be assigned for each affected cranial nerve. The DBQ covers both CN V and CN VII.
- Traumatic Brain Injury (TBI) Head trauma is a common etiology for trigeminal nerve injury, particularly at the skull base. If TBI is service-connected, trigeminal nerve paralysis may be ratable as a residual of TBI or as a separate condition. The relationship should be clearly documented in the nexus.
- Headaches, Including Migraine The trigeminal nerve is the primary mediator of head and facial pain pathways. Trigeminal nerve dysfunction may co-exist with or contribute to service-connected migraines or other headache disorders. These may be separately ratable conditions.
- Multiple Sclerosis (MS) Trigeminal neuralgia and trigeminal nerve palsy are well-recognized manifestations of multiple sclerosis due to demyelination of the trigeminal root or central pathways. If MS is service-connected, trigeminal manifestations are typically rated as a residual under the MS rating or separately under DC 8205/8405.
- Dry Eye Syndrome / Corneal Disorders Loss of corneal sensation from V1 (ophthalmic) branch damage leads to neurotrophic keratitis - a serious corneal condition caused by loss of the protective trigeminal reflex. This may be separately ratable under the organs of special sense schedule and should be evaluated by ophthalmology.
